Rush Limbaugh slammed President Barack Obama’s appearance on “The Tonight Show with Jay Leno,” saying he “diminished” the presidency by discussing serious matters on the late-night comedy show.

“The presidency was diminished last night, the country, talk about being respected or loved by people around the world,” the conservative radio host said on his Wednesday show according to the transcript. “There’s nothing wrong with late-night comedy shows, but this would not have happened with any prior president. Matters of such consequence, matters of such seriousness would have been dealt with in a far more serious and appropriate way and forum and time of day.”

Limbaugh accused the president of making issues — including the nation’s complicated relationship with Russia, especially in light of NSA leaker’s Edward Snowden’s asylum there — appear as a joke by choosing the show for one of his rare public sit-downs.

“All of it was treated as a joke. All of it was treated as unserious, halfhearted, nothing really to be concerned about,” he said. “He went there for a specific reason, to accomplish specific things. I don’t know whether he thinks he did or not, but what he did was diminish the office of the presidency. He diminished the country. I just think it’s a shame.”

“Made the country look small, made the presidency look small. No, I don’t think JFK went on Jack Paar to talk about the Cuban missile crisis. I was just thinking about that, but I don’t think JFK did that. That might be too old, long ago for some of you youngsters out there. Jack Paar was the original Johnny Carson. I don’t think JFK went on the Jack Paar show to talk about the Cuban missile crisis,” Limbaugh added. “It was an … unserious appearance. It made a mockery of what are serious world events.”
